(Specification)Standard Specification for Foot Protection for Chainsaw Users
Standard Specification for Foot Protection for Chainsaw Users
ABSTRACT
This specification prescribes the minimum requirements for the design, performance, testing, and certification of footwear and foot protective devices that, when worn by operators of power chain saws, shall provide cut resistance protection to their feet, and thereby reducing foot injuries caused by close contact with the running saw chain. The footwear and foot protective devices shall be constructed with suitable fit and flexibility so as to provide sufficient foot comfort and normal maneuverability to perform intended tasks, while maintaining satisfactory functionality and efficacy for the duration of its regular use throughout seasonal climatic variations. Completed footwear shall be inspected and certified as specified, and maintained in accordance with the manufacturer's instructions.
SCOPE
1.1 This specification covers minimum requirements for the design, performance, testing, and certification of footwear and foot protective devices designed to provide cut resistance protection to the feet of operators of power chainsaws.
1.2 The objective of this specification is to prescribe fit, function, and performance criteria for footwear and foot protective devices worn by chainsaw operators, which are intended to reduce foot injuries caused by contact with a running power saw chain.
1.3 This specification is not intended to serve as a detailed manufacturing or purchasing specification, but can be referenced in purchase contracts to ensure that minimum performance requirements are met.
1.4 Controlled laboratory tests used to determine compliance with the performance requirements of this specification shall not be deemed as establishing performance levels for all situations to which chainsaw operators may be exposed.
1.5 Mandatory requirements are indicated by the use of the word shall; recommendations and advisory information is indicated by the use of the word should.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
